This is a scene from the original English dub of the first Kimba The White Lion episode, recorded in November, 1965. It's still Billie Lou Watt as Kimba and his mother, and Ray Owens as the narrator, but it's a whole different performance than what is commonly known, because this soundtrack was replaced with a new performance in August, 1966. It's only recently that the whole 1965 original was recovered. Check out the Lost Episode page at www.Kimba.US.
